PATH OPTIMIZATION OF MOBILE SINK FOR ENERGY EFFICIENT DATA TRANSMISSION

The sink node movement along with fixed path can minimize the energy utilization in Wireless Sensor Networks (WSN). This technique brings significant challenges for data collection and energy consumption. To overcome the issue several combinatorial optimization techniques are considered. The optimization of the path is to solve the Path Stop Point (PSP). The path of the mobile sink is determined based on various constraints to avoid data loss and more energy consumption. The path determination mainly based on flow constraint, energy constraint, and cost constraint. This paper reviews about various optimization techniques available and focuses to overcome the constraint problem.
